Abstract

Engineering Engineering, Electrical & Electronic Optics Physical Sciences Science & Technology Technology Telecommunications
A phase switching prescaler based on odd phase signals is proposed. This technique makes it possible to use the ultra-low power single-ended Injection Locked Frequency divider (ILFD) with an odd division ratio in the dual-modulus prescaler design. A divide-by-23/24 dual-modulus prescaler is proposed based on an ultra-low power divide-by-3 ILFD. In the 2.4 GHz band, its power consumption is only 1 mW with a 1.5 V supply voltage. It is also capable of operating with a frequency up to 5.2 GHz with 1.8 V supply voltage.
